- The images have been obtained with the time resolution up to sub millisecond. 并对结果进行了讨论。
- In theory, the first step toward producing a millisecond pulsar is the formation of a neutron star when a massive star goes supernova. 理论上,形成一颗毫秒脉冲星的第一步,是一个大质量恒星在成为超新星而爆发后留下的中子星。
- An X-ray binary system has been formed, and the neutron star has made the crucial second step toward becoming a millisecond pulsar. 射线双星就这样形成了,于是这颗中子星就向成为毫秒脉冲星迈出了关键的第二步。
- With the implementing of the millisecond pulsar timing array( PTA), the application of pulsar time will become possible in the near future. 随着脉冲星计时阵的实施,脉冲星时的应用已为期不远。
- The discovery of the millisecond pulsar PSR 1937 + 214 is one of the most important events in astrophysics in recent years. 毫秒脉冲星PSR1937+214的发现是近几年天体物理学中的一次重要事件。
- A millisecond pulsar is a supercompact neutron star, whose spin is highly accelerated by mass transferred from a companion star. 毫秒脉冲星是密度极大的中子星,其旋转被从伴星转移来的的物质大大地加快了。
- They suggest that these similarities between a known millisecond pulsar and a known X-ray binary provide the long-sought link between these types of objects. 他们认为,一个已知的毫秒脉冲星与一个已知的X射线双星之间的这种相似性,为我们提示了这两类天体间长期未知的内在联系。
- Finally, due to the rapid rotation of the neutron star, or the evolution of the companion, the infall of matter stops, the X-ray emission declines, and the neutron star emerges as a radio-emitting millisecond pulsar. 最后,由于中子星疾速的自转,或是伴星自身的演化,物质的流入停止,X射线辐射减弱,这颗中子星就呈现出了毫秒脉冲星的面目。
- It links a millisecond pulsar with many of the properties of an X-ray binary, to J1808, an X-ray binary that behaves in many ways like a millisecond pulsar, thus providing a strong chain of evidence to support the theory. 然而直到目前,决定性的证据还未获得,因为介于第一和第二步之间的过渡天体还几乎不为人所知。
- The possible application may include time keeping by combining of millisecond pulsar with atomic clocks, constructing an ensemble pulsar time scale, detecting the error in atomic time scale via PTA and so on. 可能的应用包括毫秒脉冲星与原子钟结合守时、立综合脉冲星时和用脉冲星计时阵检测原子时误差等方面。
- It is possible that an average pulsar time scale PTens may be deduced through along-term stability algorithm using precision timing data from more millisecond pulsars. 采用合适的长期稳定度算法,由多颗毫秒脉冲星计时观测可以建立综合脉冲星时间尺度。
- Progress on Millisecond Pulsar Timing Observations 毫秒脉冲星计时观测进展
- In this paper we describe the characteristic of time and physics of pulsars, and the significance of study,as well as recent progress of millisecond pulsar timing theory and techniques in the world. 介绍脉冲星的时间频率特征,脉冲星时间研究的意义,毫秒脉冲星计时理论方法和技术方面的研究进展,对其中的关键问题给予讨论。
- I had to sub for the referee, who was sick. 裁判病了,我得代为裁判。
- Most astronomers accept the binary spin-up scenario for creating millisecond pulsars because they have observed neutron stars speeding up in X-ray binary systems, and almost all radio millisecond pulsars are observed to be in binary systems. 多数天文家接受这个假想的模式,因为他们已经在X射线双星系统中观测到了中子星的加速现象,而且几乎所有的毫秒脉冲星都被发现时处于双星系统中。
